[Chemical constituents from roots and rhizomes of Panax ginseng cultivated in Jilin province].[Pubmed:24380303]
Zhongguo Zhong Yao Za Zhi. 2013 Sep;38(17):2807-17.
The chemical constituents of the roots and rhizomes of Panax ginseng were systematically investigated by various column chromatographic methods including Amberlite XAD-4 macroporous adsorptive resins and silica gel as well as high-performance liquid chromatography, and their chemical structures were identified by physico-chemical properties and spectral analyses. Twenty-eight compounds were isolated from the 70% ethanolic-aqueous extract and identified as koryoginsenoside R1 (1), ginsenoside Rg1 (2), ginsenoside Rf (3), notoginsenoside R2 (4), ginsenoside Rg2 (5), notoginsenoside Fe (6), ginsenjilinol (7), ginsenoside Re5 (8), noto-ginsenoside N (9), notoginsenoside R1 (10), ginsenoside Re2 (11), ginsenoside Re1 (12), ginsenoside Re (13), ginsenoside Rs2 (14), ginsenoside Ro methyl ester (15), ginsenoside Rd (16), ginsenoside Re3 (17), ginsenoside Re4 (18), 20-gluco-ginsenoside Rf (19), ginsenoside Ro (20), ginsenoside Rc (21), quinquenoside-R1 (22), ginsenoside Ra2 (23), ginsenoside Rb1 (24), Ginsenoside Ra1 (25), ginsenoside Ra3 (26), ginsenoside Rb2 (27), and notoginsenoside R4 (28). All isolated compounds are 20 (S) -protopanaxadiol or protopanaxatriol type triterpenoid saponins. Compound 1 was isolated from the roots and rhizomes of P. ginseng cultivated in Jilin province for the first time and compound 6 was isolated from the roots and rhizomes of P. ginseng for the first time. The 1H-NMR data of compounds 6, 14 and 19 were assigned for the first time.
Purification and characterization of ginsenoside Ra-hydrolyzing beta-D-xylosidase from Bifidobacterium breve K-110, a human intestinal anaerobic bacterium.[Pubmed:12913270]
Biol Pharm Bull. 2003 Aug;26(8):1170-3.
Beta-D-Xylosidase (EC 3.2.1.37) has been purified from ginsenoside Ra-metabolizing Bifidobacterium breve K-110, which was isolated from human intestinal microflora. beta-D-Xylosidase was purified to apparent homogeneity by a combination of ammonium sulfate precipitation, QAE-cellulose, butyl-toyopearl, hydroxyapatit and Q-Sepharose column chromatographies with the final specific activity of 51.8 micromol/min/mg. Molecular weight of beta-D-xylosidase is 49 kDa by SDS-PAGE and gel filtration, which consisted of a single subunit. beta-D-Xylosidase showed optimal activity at pH 5.0 and 37 degrees C. The purified enzyme was potently inhibited by PCMS. beta-D-Xylosidase acted to the greatest extent on p-nitrophenyl-beta-D-xylopyranoside, followed by Ginsenoside Ra1 and ginsenoside Ra2. This enzyme hydrolyzed xylan to xylose, but did not act on p-nitrophenyl-beta-glucopyranoside, p-nitrophenyl-beta-galactopyranoside or p-nitrophenyl-beta-D-fucopyranoside. These findings suggest that this is the first reported purification of ginsenoside-hydrolyzing beta-D-xylosidase from an anaerobic Bifidobacterium sp.
Cloning and characterization of ginsenoside Ra1-hydrolyzing beta-D-xylosidase from Bifidobacterium breve K-110.[Pubmed:22534302]
J Microbiol Biotechnol. 2012 Apr;22(4):535-40.
beta-D-Xylosidase (E.C. 3.2.1.37) from Bifidobacterium breve K-110, which hydrolyzes Ginsenoside Ra1 to ginsenoside Rb2, was cloned and expressed in Escherichia coli. The (His6)-tagged recombinant enzyme, designated as XlyBK- 110, was efficiently purified using Ni(2)(+)-affinity chromatography (109.9-fold, 84% yield). The molecular mass of XylBK- 100 was found to be 55.7 kDa by SDS-PAGE. Its sequence revealed a 1,347 bp open reading frame (ORF) encoding a protein containing 448 amino acids, which showed 82% identity (DNA) to the previously reported glycosyl hydrolase family 30 of Bifidobacterium adolescentis ATCC 15703. The Km and Vmax values toward p-nitrophenyl-beta-D-xylopyranoside (pNPX) were 1.45mM and 10.75 micromol/min/mg, respectively. This enzyme had pH and temperature optima at 6.0 and 45 degrees C, respectively. XylBK-110 acted to the greatest extent on xyloglucosyl kakkalide, followed by pNPX and Ginsenoside Ra1, but did not act on p-nitrophenyl-alpha-Larabinofuranoside, p-nitrophenyl-beta-D-glucopyranoside, or p-nitrophenyl-beta-D-fucopyranoside. In conclusion, this is the first report on the cloning and expression of beta-Dxylosidase- hydrolyzing Ginsenoside Ra1 and kakkalide from human intestinal microflora.
